Working things out?

I dreamed about Mum for the first time (that I can recall) the night before last.
It was strange because I don't feel there was a sense of good or bad about the dream, I just woke up feeling sad because I was thinking about her, but it wasn't a sad dream as such.
I guess my brain is slowly starting to sort through things.  I do feel at times like I have a spot of PTSD.  I get little flashbacks, particularly to that most awful time when we first realised something was wrong, and she was in such a mess...
But I'm trying to counter that with happy memories.  I found some old photos last night, it's hard to spend too long looking at them but I love to see her smiling face.
